The very existence of a word created by the prisoners themselves from such an acronym is a tribute to human spirit. Some of these people spent 20+ years in prison with their only crime being that they did not agree with those in power. Many of them died in prison. Yet, they were able to use a certain sense of humor in creating the word to describe their own situation.

I have personally met many mukls in 1968, even one who had just been released days before!
